Answer:
Answer 1 :-
Electrostatic Potential and Capacitance
Electrostatic Potential and CapacitanceElectric potential at a point in an electric field, is defined as the amount of work done in order to move a unit positive charge from infinity to that point along any path, against the electrostatic forces, with acceleration zero.
Answer 2 :-
No work is required to move a charge from one point to another on the equipotential surface. In other words, any surface with the same electric potential at every point is termed as an equipotential surface.
Again Answer 1 :-
Sorry I don't know the Answer..
Again Answer 2 :-
In the picture number 1
Answer 3 :-
In second picture
Answer 4 :-
The net effect of the dielectric is to increase the amount of charge a capacitor can store for a given potential difference. The whole point of using a capacitor is to store charge, so coming up with a way to store more charge for the same amount of effort is a good thing.
Answer 5 :-
The difference in the effective capacity of two similar capacitors when joined in series and then in parallel is 6μF.
Answer 6 :-
In third , fourth , fifth picture
Answer 7 :-
Sorry dear I don't know the answer
Answer 8 :-
Sorry dear I don't know the answer
Answer 9 :-
The energy stored in a capacitor can be expressed in three ways: Ecap=QV2=CV22=Q22C E cap = QV 2 = CV 2 2 = Q 2 2 C , where Q is the charge, V is the voltage, and C is the capacitance of the capacitor. The energy is in joules when the charge is in coulombs, voltage is in volts, and capacitance is in farads.
